A New Paradigm for Illness Monitoring and Relapse Prevention in Schizophrenia

March 28, 2019 updated by: Dartmouth-Hitchcock Medical Center
This study was a 2-arm randomized control trial (RCT) designed to test a multi-modal smartphone data collection system that provided mobile monitoring of schizophrenia to detect early signs of relapse. The RCT compared an arm with participants who received treatment as usual with an arm that received the smartphone system for a year.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
149

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) criteria for schizophrenia, schizoaffective disorder, or psychosis not otherwise specified based on a chart diagnosis
  • 18 years or older
  • An inpatient psychiatric hospitalization, daytime psychiatric hospitalization, outpatient crisis management, or short-term psychiatric hospital emergency room within 12 months before study entry
  • Willing and able to provide informed consent

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Device: Smartphone
Participants in the smartphone intervention arm received treatment as usual in addition to receiving a smartphone with the study application. The study application identified relapse risk and prompted the clinical team to provide enhanced services.
Behavioral: Device: Smartphone
Active Comparator: Treatment as Usual
Treatment as usual included outpatient case management, linkage to services and medication monitoring.
Behavioral: Treatment as usual

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Relapses in Participants
Time Frame: 1 year
A count of participants who experienced relapse, as defined as one of the following events: psychiatric hospitalization, a significant increase in the level of psychiatric care (i.e. frequency and intensity of services), an increase in medication in addition to a 25% increase in Brief Psychiatric Rating Scale (BPRS) from last assessment, suicidal or homicidal ideation that was clinically significant in the investigator's judgement, deliberate self-injury, violent behavior resulting in damage to another person or property.
1 year
Time to Relapse
Time Frame: From randomization date until first relapse (evaluated approximately every 3 months until their last study visit which occurred approximately 12 months from randomization for those who completed the study).
Time to first relapse was defined as the time from randomization until the first relapse. Participants who did not experience a relapse were censored at their last known time relapse-free. Time-to-first relapse was estimated using the Kaplan-Meier method.
From randomization date until first relapse (evaluated approximately every 3 months until their last study visit which occurred approximately 12 months from randomization for those who completed the study).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Psychotic Symptom Severity
Time Frame: Assessed at baseline and every three months for one year.
Psychotic symptom severity assessed using the Brief Psychiatric Rating Scale (BPRS). This is an 18-item scale that rates severity of positive symptoms (including auditory hallucinations and persecutory ideation), and mood and behavioral symptoms. Items are rated by a clinical assessor on a scale of 1 (absent) to 7 (very severe). Total scores range from 18-126. Higher scores indicate worse symptoms.
Assessed at baseline and every three months for one year.
Depression
Time Frame: Assessed at baseline and every three months for one year.
Depression measured using the Calgary Depression Scales (CDSS). This is a 9-item assessment with values of 0 (absent) to 3 (severe) of depressive symptoms separate from positive, negative and extrapyramidal symptoms in people with schizophrenia. Total scores range from 0-27. A higher score indicates more severe symptoms.
Assessed at baseline and every three months for one year.
Social Functioning
Time Frame: Assessed at baseline and every three months for one year.
Social Functioning was assessed using the Social Functioning Scale (SFS). This is a 76-item questionnaire that assesses various aspects of social functioning and generates a number of subscale scores including social withdrawal, interpersonal behavior, pro-social activities, and an overall score of social functioning. The item values range from 0 (almost never) to 3 (often). Total scores range from 0-228. A higher score indicates greater social functioning.
Assessed at baseline and every three months for one year.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
